I would strongly recommend to Delta pilots to NOT bid the A320 when the time comes. It is hard to fly and the seats are extremely uncomfortable. Flying an Airbus is absolute torture after flying a Boeing. If you are on the 320, you also have to fly the 319 which only has 124 seats. It is the same size as the DC-9-50. You are much better off on the MD-80's and 737's.
How many narrowbody airbuses does NWA have?
How many DC9's currently flying?
How many pilots do you crew per airplane on the NB at NWA?
